The escalating demand for natural resources within the construction industry is progressing upward. At the same time, however, there is a great concern regarding the depletion of these resources. This review paper emphasizes the significance of utilizing alternative aggregate materials in concrete. Particularly, it aims to explore replacing …
In this context, the paper reviews the strategies proposed in the use of limestone fine waste, especially for concrete, and discusses an experimental program intended to assess the mechanical properties of concrete made with the fine limestone waste produced in the area of Trapani, as a partial substitute of fine aggregate (sand).

At first, the optimum replacement of aluminum dross without using quarry dust was determined at a constant percentage of fly ash-15% based on the strength results. Later, by introducing the optimum substitution of aluminum dross with cement and fly ash, the quarry dust was partially replaced at 10, 20, 30, and 40% of river sand to determine …
3.1.6 Quarry Dust Quarry dust, a waste product of the crushing process, is a concentrated material that can be used as aggregates for concreting, particularly as fine aggregates. The rock is crushed into different sizes during quarrying activities; the dust produced during the process is referred to as quarry dust and it is created as trash.
Quarry rock dust (QRD), a waste obtained during the quarrying process is a significant source of air pollution yet has the potential of becoming a …

In the universe of landscaping and hardscaping, one material often gets overlooked, yet holds the key to many successful projects – stone dust.This byproduct of crushing stones is more than what it appears to be. Also known as quarry dust, stone dust is a highly versatile substance, prized for its multitude of uses.It serves as an important …
The production of aggregate for use in concrete production yielded a significant amount of fines fraction during the crushing operation at the quarry. The fines fraction, also widely known as quarry dust (QD), poses environmental risks such as land and air pollution in the absence of a proper disposal channel. In recent years, numerous …
